Title: Improvements in or relating to automatic aperture setting mechanisms for cameras
Inventor: DUDSON MALCOLM FOX
IPC: G03B7/085
Filed: 1960-09-09
Abstract: 923,380. Photographic control of milling machines. S. SMITH & SONS (ENGLAND) Ltd. Sept. 8, 1961 [Sept. 9, 1960], No. 31188/60. Class 40 (3). [Also in Groups XX, XXII and XXIV] An automatic camera aperture control system includes a member shaped according to the response of the remainder of the system so as to compensate for variations from an ideal response. In a system of the type in which a chopper 18, Fig. 3, senses the position of a meter pointer 13 by clamping it against an anvil 16, the edge 17 of anvil 16 is shaped in accordance with the response of the photocell-meter system to a light flux varying according to a known programme. Anvil shaping system.-The photo-cell, Fig. 4, receives light from a lamp 35 through a variable attenuator 34 comprising relatively rotatable polarizers. A constant-speed motor 30 rotates a shaft 32 according to a function #t. The linkage 33 adjusts attenuator 34 so that the light falling on photo-cell 36 will, for ideal system response, cause a movement of pointer 37a of #t. A photo-electric follower 38 (see below) measures the actual pointer position #a. #t and #a are fed to a differential 40 which generates d#(=#t - #a), the deviation to be corrected. #a is also fed to a linkage 42 which generates a function g(#) which is the amount that edge 17 must deviate from a straight line to compensate unit deviation of response for a given #a. Linkage 42 generates g(#)d# and this is applied to a milling machine to move it perpendicular to the edge 17 whilst #a drives it parallel to edge 17. The photo-electric follower system comprises a bracket 60, Fig. 6, carrying a light source 63a and two photo-cells in separate halves of a box 61. As pointer 37a moves it varies the relative amount of light passing through apertures 63 to the photo-cells, the outputs of which are fed to a difference amplifier controlling a servomotor 68 to maintain the illumination of the cells equal. The #a signal is picked off from a gear-wheel 70. Specification 899,106 is referred to.
